BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a recording/reproducing device-integrated television, a recording/reproducing device and a recording/reproducing device-integrated electronic apparatus, and more particularly, it relates to a recording/reproducing device-integrated television, a recording/reproducing device and a recording/reproducing device-integrated electronic apparatus comprising a door member arranged on an opening of a housing.

2. Description of the Background Art

A recording/reproducing device rotatably mounted on a door (door member) having a pair of rotary shafts in an opening of a housing is known in general, as disclosed in each of Japanese Patent Laying-Open Nos. 2000-331470 and 2004-55024, for example.

The aforementioned Japanese Patent Laying-Open No. 2000-331470 discloses an MD player (recording/reproducing device) in which a torsion spring (spring member) is arranged in the vicinity of a rotary shaft and first and second arm portions (ends) of the torsion spring are so arranged as to hold support portions of a door and a housing therebetween. A first arm portion of the door of the MD player is engaged with a stop projection (stop portion) formed on a front surface of the door. In the MD player, when the door is rotated forward, the first arm portion of the torsion spring rotates following the rotation of the door, while the second arm portion of the torsion spring engages with a first side surface of the support portion of the housing. When the door is rotated backward, the second arm portion of the torsion spring rotates following the rotation of the door, and the first arm portion of the torsion spring engages with a second side surface of the support portion of the housing. Thus, in the MD player, the torsion spring urges the door in a direction (direction in which the door is closed) opposite to a direction in which the door is rotated, when the door is rotated. In the MD player, when the door rotates backward, the first arm portion of the torsion spring engages with the second side surface of the support portion of the housing to separate from the door. Thus, the first arm portion of the torsion spring and the stop projection of the door disengage from each other.

The aforementioned Japanese Patent Laying-Open No. 2004-55024 discloses a magnetic recording/reproducing device (recording/reproducing device) formed with a notch in an upper edge, formed on both side of the notch with a pair of stop shafts extending inside to be opposed to each other, and mounted with a spring (spring member) constituted by a torsion coil spring urging the door against the pair of stop shafts for bringing into a closed state. In the magnetic recording/reproducing device, the interval between the pair of stop shafts provided in the door is so formed as to be smaller than the length of the spring constituted by the torsion coil spring. Therefore, when the spring constituted by the torsion coil spring is mounted on the pair of stop shafts, a first end of the spring is inserted into one of the pair of stop shafts in an oblique direction such that a second end of the spring reaches a position to be opposed to the other stop shaft. Thereafter the second end of the spring is inserted into the other stop shaft.

However, in the MD player disclosed in the aforementioned Japanese Patent Laying-Open No. 2000-331470, as hereinabove described, when the door is rotated backward, the first arm portion of the torsion spring and the stop projection of the door disengage from each other. Therefore, when the door is rotated backward, in a case where the rotary shaft of the door is detached from the housing in a state where the first arm portion of the torsion spring and the stop projection of the door disengage from each other, the torsion spring arranged in the vicinity of the rotary shaft disadvantageously comes off from the door.

In the magnetic recording/reproducing device disclosed in the aforementioned Japanese Patent Laying-Open No. 2004-55024, the spring constituted by the torsion coil spring is mounted on the pair of stop shafts dissimilarly to the MD player disclosed in the aforementioned Japanese Patent Laying-Open No. 2000-331470, whereby it is possible to inhibit the spring from disadvantageously coming off from the door also in a case where the rotary shaft of the door is detached from the housing. On the other hand, in the magnetic recording/reproducing device in Japanese Patent Laying-Open No. 2004-55024, the interval between the pair of stop shafts provided in the door is smaller than the length of the spring constituted by the torsion coil spring, whereby it is disadvantageously difficult to mount the spring constituted by the torsion coil spring on the pair of stop shafts of the door. In other words, when the spring constituted by the torsion coil spring is mounted on the pair of stop shafts, the first end of the spring is inserted into one of the pair of stop shafts in the oblique direction such that the second end of the spring reaches the position to be opposed to the other stop shaft. Thereafter the second end of the spring is required to be inserted into the other stop shaft. Thus, work for mounting the spring on the door is disadvantageously complicated. Consequently, in the aforementioned Japanese Patent Laying-Open No. 2004-55024, it is disadvantageously difficult to improve workability for mounting the spring on the door.

The door portion 5 a made of resin is so formed as to be elastically deformable when the door member 5 is mounted on the cabinet 2. A contact portion 51 a (see FIG. 4) is formed on a front surface between one of the rotary shafts 5 b of the door portion 5 a and the notch 5 c.

The cylindrical rotary shafts 5 b of the door member 5 have the diameter D2 (see FIG. 2) which is the substantially same as the diameter D1 of the circular rotary shaft receiving holes 21 d. The pair of rotary shafts 5 b are inserted into the rotary shaft receiving holes 21 d of the cabinet 2 respectively, whereby the door member 5 is rotatably mounted about the rotary shafts 5 b. As shown in FIG. 5, the notch 5 c of the door member 5 is formed closer to a center (along arrow A) of the door member 5 along an axial direction of the rotary shafts 5 b at the interval L5 (see FIG. 5) from the one of the rotary shafts 5 b. The door portion 5 a is located parallel to a front surface of the cabinet 2, whereby the pair of rotation regulating portions 5 d of door member 5 come into contact with an inner surface of the cabinet 2 when the door member 5 is in a closed state. Thus, the door member 5 urged toward an outer surface of the cabinet 2 by the coil spring 6 can be inhibited from projecting toward the outer surface of the cabinet 2.

According to the embodiment, the coil spring 6 includes a coil portion 6 a, a first end 6 b and a second end 6 c as shown in FIGS. 3 to 5. The coil portion 6 a of the coil spring 6 has the inner diameter D3 (see FIG. 4) larger than diameter D2 (see FIG. 4) of the rotary shafts 5 b of the door member 5. The coil portion 6 a has a function of urging the door member 5 along arrow A by a function of the compression coil spring and urging the door member 5 along arrow B by a function of a torsion coil spring in a state where the door member 5 is mounted on the cabinet 2. The first end 6 b of the coil spring 6 is so formed as to extend in a direction substantially perpendicular to a length direction of the coil portion 6 a.

According to the embodiment, the second end 6 c of the coil spring 6 includes a coupling portion 61 c so formed as to extend along the length direction of the coil portion 6 a, an engaging portion 62 c so formed as to extend in a direction substantially perpendicular to the length direction of the coil portion 6 a and an engaging portion 63 c. The engaging portion 63 c is inclined by a prescribed angle with respect to a direction in which the engaging portion 62 c extends while being inclined by a prescribed angle with respect to the length direction of the coil portion 6 a, as shown in FIGS. 4 and 5. The coupling portion 61 c of the second end 6 c has the length L6 (see FIG. 5) larger than the interval L5 (see FIG. 5) from the one of the rotary shafts 5 b to the notch 5 c. The coupling portion 61 c is elastically deformed, whereby the engaging portion 63 c arranged on a front surface of the door portion 5 a can be arranged on a back surface of the door portion 5 a. The engaging portion 62 c is an example of the “first engaging portion” in the present invention, the engaging portion 63 c is an example of the “second engaging portion” in the present invention.

The coupling portion 61 c has a function of regulating rotation of the coil spring 6 in a direction C by coming into contact with the contact portion 51 a (see FIG. 4) of the door portion 5 a in a state where the coil spring 6 is mounted on the door member 5. The engaging portion 63 c has a function of regulating rotation of the coil spring 6 in a direction B by coming into contact with the back surface of the door portion 5 a in a state where the coil spring 6 is mounted on the door member 5. Thus, the rotation of the coil spring 6 in the B direction and the C direction is regularly regulated in a state where the coil spring 6 is mounted on the door member 5, whereby in a case where the coil spring 6 moves along arrow D (see FIG. 3), the coil spring 6 is so formed that movement of the coil spring 6 along arrow D (see FIG. 3) can be regulated by regularly engaging the engaging portion 62 c with the notch 5 c.

The engaging portions 62 c and 63 c of the coil spring 6 are so provided as to come into contact with the back surface of the door portion 5 a in a state where the door member 5 is mounted on the cabinet 2.
